Which of the following is true regarding periapical cementoma?

Periapical cementoma is a type of benign lesion that typically occurs at the apex of a tooth root and is associated with the cementum, which is the hard tissue covering the roots of teeth. In the case of periapical cementoma, the affected teeth usually remain vital. This means that the nerve and blood supply inside the tooth are intact, and the tooth is still alive.

The vitality of the teeth is an important characteristic of periapical cementomas because it differentiates them from other types of periapical lesions, such as periapical granulomas or abscesses, which usually occur in the setting of non-vital teeth. Thus, the presence of a continuing blood and nerve supply indicates that the health of the pulp is maintained, regardless of the lesion's presence.

In relation to the other options, there are clinical scenarios where periapical cementoma can be asymptomatic, can affect teeth other than molars, as well as the fact that not all affected teeth will necessarily be non-vital. These distinguishing features help to clarify the unique nature of periapical cementomas and reinforce the correctness of the assertion regarding the vitality of the teeth involved.
